Study Notes
Translation
- Translation takes place in the cytoplasm after mRNA exits the nucleus through nuclear pores.
- mRNA binds to ribosomes, where protein synthesis occurs.
- Codons, consisting of three nucleotide bases on mRNA, are matched with anticodons on transfer RNA (tRNA).
- tRNA transports specific amino acids from the cytoplasm to the ribosome-mRNA complex, initiating polypeptide chain formation.
- The translation process continues until the polypeptide chain is fully synthesized.
DNA Replication
- DNA replication occurs during interphase when DNA is housed in the nucleus within chromosomes.
- Each DNA strand separates and serves as a template for producing a complementary new strand.
- Newly paired nucleotides join with existing nucleotides facilitated by enzymes, forming a new DNA strand.
- The nucleotide sequence on the template strand dictates the sequence on the newly synthesized strand.
- DNA replication results in the formation of two identical chromatids connected at a centromere, constituting one chromosome.
The Cell Cycle
- Cell division is essential for growth, development, and the replacement of damaged or dead cells.
- The cell cycle encompasses two primary phases: interphase (non-dividing phase) and mitosis (cell division phase).
- A cell predominantly exists in interphase, where it carries out normal metabolic functions and prepares for division.
